What!?
Not a word that the $20 million prize is more than the cost of a moon flight and that afterwards there'd be enough to buy all kinds of HEO/LEOs? No comments? Seems (to my way of thunking) like we could build a lander and still have a bunch millions left; a good profit motive for a semi-private business to back us.
AMSAT has everything needed to make an excellent business case to go after the $20m. So... Why don't AMSAT folks do a business/grant/ plan and go after seed money, with the goal of collecting the $20 million. It's just sitting there, from Google, waiting for geniuses like we already have to go after it. No free money; just available to those who want it bad enough.

Seriously folks, AMSAT is not some big monolith that you send all your prayers to and wait for them to happen. We are AMSAT. If you feel strongly about a project, put together a plan and a team and bring it to the BOD prepared to describe how you are going to accomplish it. The problem is AMSAT is chronically short of those who want to really help. We have three empty officer positions. We only had enough BOD candidates to fill the seats available and the alternate. We have a list in every Journal of jobs we need help with, but very few have stepped forward to actually help. We need folks with skills in:
Marketing Sales Software Engineering Hardware Engineering PC Based Software Design Web design and maintenance Project Management Documentation Hardware Testing Software Testing Hardware Prototyping Specific Area Web site information maintenance Video Recording, digital conversion and editing Writing Technical or Instructional Material Educational Activities Promoting AMSAT as an Area Coordinator
...and whatever else you think might help.
See Page 19 of the last AMSAT Journal. If you don't get the Journal, join AMSAT so you can have a say in what we do by whom you elect to the BOD. Arguing about it on the internet is one thing, but doing something about it takes another level of commitment.

Hello all,
This "moon" thread has prompted some interesting thoughts. Perhaps some of you might like to channel that talk into action.
I chair the AMSAT Engineering Task Force (ETF), of which Drew Glasbrenner is a member. He has already noted the need for volunteers. I'm going to comment on one of the current ETF tasks that can use your support.
For the past two years we have defined the satellite features we should have for a HEO (high earth orbit) launch opportunity. We stand prepared to embark on that project "IF" the funds (more than $8 million) are made available to us. Well folks - we're no closer to landing $8 mil plus today then we were two years ago. The situation is no different then the financial problems facing the P3E project.
So, the revised Mission Vision resulting from the October 2008 Board meeting tasked us to prepare a strategy to get us ready for "ANY LAUNCH" opportunity that we uncover(yes - that includes LEOs). Our satellite sub-system module development program is making good progress to meet that object.
That said - we are starting to define the "features" we'd like to see on our next "realistic and attainable" satellite project. Assuming it could be a LEO launch, possibly a 1X to 3X CubeSat style satellite, WHAT WOULD YOU LIKE TO SEE ON BOARD, by way of communication, science experiments, etc.
Let's see how creative you can be, but let's temper our desires with realism.
Send me your list (off line preferably). I'll sort the responses and report back to the -bb, and the Board, with what you folks are thinking about. If there is an aspect of satellite design or a project you're keen on doing, let me know that too. If your a students with an idea that didn't make it on you're school's CubeSat project or the project is going too slow for you - I'd like to hear from you too.
I know we keep trying to get your inputs and make you part of the solution and it usually doesn't succeed. Will this solicitation be any different??
Regards...Bill - N6GHz

Why not initially inquire of William Leijenaar PE1RAH about his completed transponder, the Mark I, Type I of which is already in space in the satellite from India?
Last heard he was looking for a standardized frame for a cubesat to place it in...work with him financially, provide him with, or aim him toward a frame and put it "on the AMSAT shelf" for the next available launch "anyone" finds.
Here is an "engineering student" (as quoted from the AMSAT website) who has accomplished all of this by himself...offer him some help as well as the big, wide world influence of AMSAT to find the NEXT launch. Who cares what orbit it is in? (that ought to start thing up again!)

Hello, I have a registered copy of NOVA and now need to interface my PC to two ICOM radios. I have an IC471 and IC275 but understand these may not work. I'm looking for recommendations on interfacing NOVA to these two radios, or a suggestion on another (economical) radio.
Any recommendations?

Hi, Dave I'm using them, and at first I powered them up the coax from my FT-847. I then went and connected a 2M bandpass filter to get rid of some 2M crud in my area, and didn't check if the filter had the center pin of the coax at DC ground or not. It did, and I popped the transistor that switches the voltage to the coax. Now I power them with separate power, using some "paired" red/black cable soldered in to a PL-259. I use an RG-58 adapter, as that takes up some of the excess space where the relatively small wires go into the back of the plug, and also provides a nice, rounded edge for the wires to rest against so the sharp edge of the PL-259 won't cut the insulation.

Dave,
I have a pair and in my case they are powered right up the coax to the rig by the IC-910H. They are very good, albeit expensive preamps, and they make a huge difference for my setup, as I have a 150 foot run of rg-8 to the antennas.

I use them as well, and REALLY like them. At Field Day, for simplicity, I power them up the coax from the IC910. Home station, they get separately powered through a sequencer. 73, Jim wb4gcs@amsat.org

Hi group- I'm installing my 2MCP22 and 436CP42 U/G antennas and find that the coax is hanging up on the Rohn tower sides near my G-5500 rotator plate. How are folks keeping the coax away from the tower sides and hanging up?
Springs? Cable ties?
I have hung it up twice and stalled the AZ/EL. I don't wanna break something so thought I'd ask for expert advice and experience and not reinvent the wheel.
Thanks in advance,

Hello Dave,
My Rohn towers use a flat top section, I wrap in a 3X loops ~ 12-15' of a flexible coax as the rotator loop. The loops are loosely layed in on the flat top plate. One end anchored with Tye wraps to the main tower and the other end anchored to the rotating mast, with another single loop to the elevation boom.
I typically use LMR 400 ultra flex as the rotator loop with N male connectors. Below the loops are 1/2" or 7/8" hard line and above the loops is LMR-400 laced onto the H or V mast.

Spring is here, time to change antennas. For sale 22XB and 738XB circular pol. antennas. 2 meter one works great but the 440 one doesn't seem right. Maybe needs new phasing lines. $200 for the pair. I have the assembly manuals and all parts seem to be there. Located in EL99bf. Silver Springs, FL 34488
